Problems solved by technology

At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insulation layer to fall off, which may cause secondary fires and secondary fires. harm, so the relevant state departments explicitly prohibit the use of organic insulation materials for external wall insulation, especially in high-rise buildings and public buildings
Among the thermal insulation materials whose combustion performance reaches the A-level standard, inorganic materials represented by mineral wool and rock wool are mainly used. However, the existing domestic products have a large gap with the requirements of architectural applications in terms of water absorption, strength, and weather resistance. If it is directly used for building wall insulation, there will be problems such as water absorption, falling, softening, etc.
In addition, the cost of Class A thermal insulation materials is much higher than that of organic materials, and the construction process is complicated. The construction cost far exceeds the cost of Class B thermal insulation materials, and its thermal insulation performance is poor and energy consumption is high, which cannot meet the current needs of the country for energy conservation and emission reduction.
[0003] Vacuum insulation panels are a new type of insulation material developed in recent years, mainly including vacuum bags and core materials. There are obvious disadvantages such as difficult drying of the core material, poor air tightness of the vacuum bag, low puncture resistance, high moisture content of the core material, fast vacuum attenuation, easy expansion of the bag, short insulation life, etc.

Embodiment 1

[0032] Embodiment 1: see figure 1 , the metal vacuum composite insulation panel is composed of shell 1, core material 2, core plate 3 and low-temperature solder 4, shell 1 is made of stainless steel plate, stainless steel plate, electro-tin plate, galvanized plate or aluminum plate with a thickness of 0.15-1.5mm It consists of thin metal plates such as alloy plates; the core material 2 is glass fiber, pearl sand, perlite, vermiculite, airgel, etc., and the core material 1 is preferably dried, packed in plastic bags, and pre-vacuumized; the core plate 3 It is a metal plate, a glass plate, a ceramic plate or a high temperature resistant polymer plate, preferably a tempered glass plate of 3-5 mm or an aluminum alloy plate of 1-2 mm. The manufacturing method of the metal vacuum composite insulation board is as follows: Firstly, two electroplated tinplates of the same size are cut out as the shell 1 to make the vacuum cavity, and the two electroplated tinplates are folded and forme...

Embodiment 2

[0033] Example 2: See Example 1 and figure 2, basically the same as Example 1, the difference is that the core board 3 is made of a high temperature resistant high polymer plastic board such as LCP board, which is directly placed in the vacuum chamber, and the metal plate forming the shell 1 is directly stamped out of the edge seal when stamping and forming The grooves used are used, and low-temperature metal solders such as tin, zinc, magnesium and their low-melting point alloys are placed in the grooves, and the airtight sealing of the vacuum chamber is completed by brazing in a vacuum furnace.

Abstract

The invention discloses a metal vacuum composite insulation plate. The metal vacuum composite insulation plate comprises a shell, a core material, a core plate and a vacuum cavity, and is characterized in that the shell is a metal plate or a metal composite plate, wherein the core material and the core plate are positioned in the vacuum cavity formed by sealing and welding the shell; the core plate or / and the core material provide the additional strength for the shell, and guarantee the flatness of the shell under atmospheric pressure; and the vacuum cavity is automatically welded and sealed in batches in a vacuum furnace under high vacuum and at high temperature. A preparation method of the metal vacuum composite insulation plate is simple in process; and the prepared metal vacuum composite insulation plate can overcome the defects of a traditional insulation plate and a traditional vacuum insulation plate, and can be improved in strength, heat insulation, sound insulation, fire prevention and decoration functions.

Description

technical field [0001] The invention relates to a vacuum insulation panel, in particular to a metal vacuum composite insulation panel and a manufacturing method thereof. Background technique [0002] my country's building energy consumption has accounted for more than 1 / 3 of the energy consumption of the whole society, and it is increasing year by year. The use of thermal insulation building materials is one of the main means to reduce building energy consumption. At present, many materials used for building exterior wall insulation are Class B insulation materials, such as polystyrene, polyurethane, foam rubber and other organic materials. These organic materials have poor heat resistance and are easy to burn. A large amount of toxic smoke can accelerate the spread of the fire; at the same time, organic materials will shrink during a fire, producing burning droplets, causing the tiles on the insulation layer to fall off, which may cause secondary fires and secondary fires. ...
